HR Glass Needlemat

HR Glass (High Resist Glass) is alkali-free aluminosilicate glass that does not contain boron oxide. This glass type fully substitutes E-glass in various aspects. The most important feature of this type of glass is its heat resistance of up to 800°C.

Advantages of HR glass fibre compared to E-glass:

• Higher chemical resistance, particularly in alkaline and water environments;
  higher heat resistance.
• Environmentally friendlier glass melting process, does not create dust emissions containing boron oxide.
